摘要： Various embodiments are described herein for a method, apparatus and system for performing multi-modal imaging using a common imaging probe having various modes of operation including a fluorescent (FL) imaging mode and at least one of an ultrasound (US) imaging mode, a photoacoustic (PA) imaging mode and a combined US/PA imaging mode. Molecular/functional information may be obtained from FL and PA imaging and anatomical information may be obtained from ultrasound (US) imaging. The system may be implemented to provide for images from each modality in real time as well as provide for co-registration of these images. Experimental results demonstrate that combining the imaging modalities does not significantly compromise the performance of each of the separate US, PA, and FL imaging techniques, while enabling multi-modality registration.

摘要： Planar waves are transmitted to a target object with an angle of wave propagation corresponding to a center position of a receive subaperture. The echo signals reflected from the target object are received by the receive subaperture, stored in a receive pattern memory and dynamic-focused. The dynamic-focused signals are then combined to form at least one beam pattern to produce an ultrasound image.

摘要： Provided is a method of dynamically reallocating a thread stack in a multi-threaded operating system, and more particularly, a method of dynamically allocating a thread stack of a multi-threaded operating system in an embedded system for wireless sensor nodes. The method includes the steps of: measuring sizes of data and non-data sections of a stack with respect to each thread; determining a new size of the non-data section of each stack based on the size of the data section of the stack measured with respect to each thread; and adjusting the size of the non-data section of each stack to the determined new size. According to the method, even without the source code analysis, an amount of memory spaces to be used can be reduced compared to that of a conventional static stack allocation method.
